MATRX HOLDER AND ELEVATOR FOR TVPOGRAPHIG MACHINES.

Specification of Letters Patent.

Patented Mar. 21., 1922.

Origin@ application filed March 15, 1918, Serial No. 222,760. Divided and this application filed July 12,

To all fecmm t may concern Be it lrnown that l, FREDERICK lil.' Larson, a citizen ot' the United States and residingr at Baltimore city, hlaryland, have invented certain new and useful Improvements in Matrix Holders and Elevators for Typographic Machines,.ot which the itollmving is a specification.

This invention relates to a matrix holder and elevator for tyqiographic machines, particularly machines ot the kind disclosed in my copending applicationk Serial No. 222,760, filed March 15, 1918. oi" which the present application is a division.

The invention relates particularly to the mechanism for receiving the matrices trom the assembler mechanism, presenting them to the mold and atter the casting operation' elevating the same to the position to be transferred to the distributing mechanism. lt is the principal aim ot' the invention to simplify the mechanism employed for accomplishing these results and toprovide a construction which is positive and rapid vin operation and which, it desired, may be easily arranged to produce repeated castings from the same matrix.

The invention in one of its embodiments is set forth in detail in the `following` speciication and illustrated in the accompanying drawings in which:

Figure l is a sectional view ot a portion oit a typographical machine. said view being taken on a vertical. plane `from trout to rear through the parts oit the mechanism constituting the present invention and other parts which cooperate therewith:

similar to Figure -lbut showing certain parts in a dillerent position; Y Figure 8 is a detailed View ot' a locking device .employed when making duplicate liinotype castingsl rReferring to the drawings in detail 1() represents generally the assembling mecha'- nism in which the matrices and siatebands are assembled to form a line in the well known manner and as set torth in my prior application above mentioned and from which mechanism the matrices are transferred to the part of the machine to which the present invention relates. 11 represents generally the mold to which the assembled matrices'are presented in casting slugs or linotypes, such mold beine of any desired construction.'

The mec anism to which the present invention particularly relates, includes a presentation slide 16 which carries lined rails 12, 13 and 15 and a movable rail 111. These rails are adapted to receive the assembled matrices and space bands .trom the assembling mechanism and support the same duri ng the casting operation and while they are elevated as hereinafter pointed out. The presentation slide is arranged to move 'torward and rearward upon guides or ways 1T and the same is also movable vertically in guide-ways 18 formed in suitable standards or rigid portions of the framework ot the machine. The presentation slide when Vin its forward position and withdrawn from the mold 'is adapted to slide vertically in said guideways 18 to carry the matrices to the second elevator and to carry the space bands associated with the matrices to thele vel of the space band magazine as fully set forth in my said prior application, the presentation slide 1 6 thus constituting the lirst elevator. The presentation slide 16 is moved rearward and forward or toward and Yfrom the casting mechanism by two pairs of elbow levers 19 pivoted to a rigid part ot the machine and which have downwardly projecting arms provided with rollers 20 running in guide grooves 21 of said slide 16. The elbow levers also have forwardly extending arms which are connected to cross bars 22 which cross bars are connected by suitable links 23. The elbow levers 19 are rocked to carry the presentation slide rearward and forward by a rod 24C which is operated by a suitable cam mechanism secure( to the main cam shaft of the machine. The detailed mechanism employed for operating said rod Y constitutes no part ot the present invention and description and illustra-tion ot the same is unnecessary. The rod 2a includes a spring linlr 25 otordinary construction, the details of which it is not necessary to illustrate.

It will Vbe understood that as the rod 24; is drawn downwardly the elbow levers will be rocked on their pivots and the presentation slide 16 will be moved rearwardly to bring the matrices against the mold. ln order that the matrices may he brought into exact register with the mold there is provided dowel pins 1la rigidly secured t0 a part of the castingy mechanism which dowel pins are adapted Vto enteropenings 16a in the presentation slide. moved upwardly the presentation slide will he drawn forwardly or away from the mold. The opera-tion of casting the slugs or linotvpes takes place while thc presentation slide carrying the matrices is in its rearward position or against the mold.

l/Vhen it is desired to cast a plurality of slugs or linotypes 'from' a single line ol matrices the rod 24 is prevented from rising;

lto its full extent and the elbow levers 19 are therefore prevented `from withdrawing the presentation slide sufficiently to engage it withthe elevatingdevice hereinafter described. This result is accomplished by interposing a pivoted block 26 in the path of a collar 27 which is secured on the rod 24. This prevents upward movement of the rod 24;, the movement oi the operatingmechanism which causesreciprocation of the krod 24 being taken up, under such condition`V by the spring link 25. vWhen the block 26 is rotated about its pivot point 26"L so as to be out oli' the path of movement ot the collar 27 a single slug' or linotype will be cast trom each line of assembled matrices. Y Y When the rod 24. is raised toits 'full extent and the presentation slide is moved to chine. It will be understood that when theV forward movement ot thepresentation slide is interrupted by vthe pivotedbloch 2G, as previously state-d, the cross har 30 will not be moved `iorwardly a suiiicient distance Ato engaoe lthe o eninp- 31v of the elevator slide p e P e 32 and the upward movement of said elevator slide will not raise theV presentation slide. When the parts are in the position shown in' Figures 1 and l the presentation slide will be raised in the guides, 18 by the upward movement of the elevator slide l/Vl'ien the rod 241 is :i ,alonso Vat its free end a roller 3a positioned to contact with the inclino 35 arranged adjacent the upper part of the guide-ways 1S. The rail la is adapted to support the matrices when it is desired to cast from the lower row of characters usually provided on the matrices and it therefore follows that when this rail is withdrawn in the manner just described the matrices will all be brought to a common level suitable for transfer to the second elevator which is'oii well known type andv which it is unnecessary/to illustrate or describe in the present application, such transfer being effected by suitable transfer mechanism Agenerally designated by the numeral 36.

To briell)T review the operation oli the device it will be understood that the matrices are assembled inV suitable lilies in Athe assembling mechanism and that such assembled lines are then transferred to the presentation slide of the present mechanism being supported on the railsuwith which such slide is provided. rlhe rod 24 is caused to move up and down by suitable cam mechanismV operated from the main Ashaft of the machine. As this rod moves downwardly the elbow levers are rocked on theirpivots which cause the presentation slide to move rearwardly against the casting mechanism. ,lifter the casting operation the rod24l moves upwardly which serves to withdraw thepresentation slide and the line of matricesv movement oit the'rodV the Vpresentation slide( with the same matrices mount-ed'thereon will be again presented to the* mold and a second slugor linotvpe ot the same character will be cast. It the upward movement ot Vthe rod. 2li-"is not interrupted the presentation slide will be-` drawn forwardly to the.

full extent of its movement and the cross p bar-30 on saidslide willenter the recessA 31 ol the elevator slide 32 and as said elev ator- Vslide is movedV upwardly the presentation slidewill he raised in the guide-ways 'i8 thus lifting'the line of matrices in position to be transerred to the second elevaton During such upward movement ol' the presentation slide the rollers carried by the elbow levers will moveitreelv inthe grooves formed in the presentatori slide and such rollers and elbow levers will therefore not interiiere with the upward or downward moveniegt el the presentation slide. its the elcifneeso vator slide 32 moves downwardly the pres-- entation slide is lowered to its original position ready to receive a new line ot assembled matrices from the assembler mechanism.

It .is obvious that various modifications and rearrangements of: the foregoing mechanism may be made without departing` i'rom the spirit of the invention and which is not limited to the particular details of construetion and operation herein described.
